Is there a good place for mole removal in the Dongdaemun-gu area?

Is it correct to go to a dermatologist for removing blackheads?

Sometimes, I hear that they do similar simple procedures at other places.

Isn't that dangerous? I'm a bit anxious because I don't know what problems there might be.

How much does it cost to remove a mole at the dermatology clinic?

I've never removed it before, but maybe because I'm getting older, it feels like the mole is getting bigger.

Have you all had this kind of experience?
